辽宁新华低品位钼矿X射线辐射预选试验研究

Study on the X-ray Radiation Preconcentration of Liaoning Xinhua Low Grade Molybdenum Ore

对辽宁新华低品位钼矿不同粒级试样进行了不同分离阈值预选效果试验,结果表明,预选指标随给料粒度的变化而变化,在其他试验条件相同的情况下,100～60 mm粒级的分选指标明显优于其他粒级,即给矿块度过大或过小均不利于分选指标的改善。

The test of Liaoning Xinhua low grade Mo ore preconcentration index according to different separation threshold value was studied. The results indicated that preconcentration index varies with the block of fceded material. Under the same test conditions, the beneficiation index of 100 -60 mm size class particle was better than the other grain-sized particles and too large or too small particles all can affect the preconcentration index adversely.
